#Calculation
This channel publishes videos on how to make calculations many times, but with this in mind, this time we have put in some patterns that even people who are not good at mental arithmetic can calculate with only multiplication tables.
As you become accustomed to the idea of decomposing expressions, you will be able to easily perform mental calculations.
Please take a look.
